While searching for an image of
Pete McShannic, I came across this very nice image of the 1888 Pittsburgh Alleghenys (I refuse to use the h-less, government-mandated-for-no-good-reason spelling of the time)... unfortunately, the players are not identified, so I'll simply offer it here for whatever it might be worth.
The full sized (1,473 × 954 pixels, file size: 728 KB) image can be seen
here and might be of some value in providing facepack images, if anyone can identify these guys...

edited to add: my guess on McShannic, based on the present facepack image, would be the fella standing second from the right...
